Special Seminar: Megan Russell: "Designing Cryogenic Readout for CMB Experiments"

Observations of the cosmic microwave background (CMB) offer a window into the early universe. Experiments such as LiteBIRD and the Simons Array are designed to measure the large-scale polarization of the CMB searching for signs of inflation. Both experiments rely on large numbers of highly sensitive bolometric transition edge sensors, and require the use of SQUID based cryogenic readout systems. In this talk, I will discuss the testing of this readout system, validation of a noise model, and an exploration of possible designs for LiteBIRD.
